High School Online Math Courses - Know The Best Resources And Curriculum

Math—the word comes in like a nightmare for some students. The complex methodology involved grasping the core concepts and then applying them to problem-solving—well, who would not be afraid?

However, math is more than just a "subject", it is the fundamental part of human logic. Not only that—mathematical problem solving builds mental discipline and logical reasoning, increasing mental rigor.

Thus, it enhances problem-solving skills and gets your brain adapted to liking rigor. What can be a better way to excel in any curriculum? Moreover, your math skills are not just limited to math as a subject itself—mathematical knowledge plays a vital role in other subjects.

According to research conducted by Dr. Tanya Evans of Stanford University, "children who know math are able to recruit certain brain regions more reliably, and have greater gray matter volume in those regions, than those who perform more poorly in math".

It is evident that great mathematical skills are a key to strengthen the brain. And in the era of automation and digitization, math-related career prospects are booming. However, students not only fail to understand the importance of mathematical knowledge but also get discouraged. Following the wrong pathway, learning from "not to the mark resources" adds to the fail.

Keeping that in mind, we have framed this article to guide high-schoolers towards the right approach. We will be discussing the overall math curriculum, electives, and the best math resources on the web. So, get ready, your magical journey towards high-school mathematics begins!

Let's first talk about the Standard High School Math Curriculum, What is it like?

The high school math curriculum varies for different states. However, forty-five states are following the Common Core Standards for maths. These standards create a more standardized math curriculum across the country. Also, it mandates the coverage of the following six content categories in high school:

  • Algebra
  • Functions
  • Modeling
  • Geometry
  • Statistics
  • Probability

As the standards are broad, they do not specify which content should be taught for each grade. Thus, there is a lot of differentiation between schools and states.

Usually, high schools decide the order of these math topics based on the results of placement tests. So, there is no specific set of rules outlining which courses you should be taking as a freshman, sophomore, etc.

The typical order of math courses followed by most students in high school is:

  • Algebra 1
  • Geometry
  • Algebra 2
  • Trigonometry
  • Pre-Calculus
  • Calculus
  • Advanced Placement Classes

However, not all schools follow this order. For instance, some schools teach algebra 2 immediately after Algebra 1 instead of putting geometry in the middle. Some schools merge trigonometry with either geometry or pre-calculus. Other schools require the students to take pre-algebra before heading towards Algebra 1 and Algebra 2. Yet, most of the high schools follow a course order similar to that mentioned above.

It should be noted that the math classes you take in freshman year are decided based on a placement test. The order may also depend on the previous math classes you have taken in middle school. For instance, if you have already read Algebra 1 in grade 8, you can directly move on to geometry. Also, it is not mandatory for every high-schooler to take Calculus or Pre-Calculus.

And What about Individual math courses? What is the curriculum?

The high school curriculum requires a student to take a variety of classes in different core subject areas. One of these is maths, requiring the high-schoolers to complete at least three years of the coursework. All the classes that fall under the math curriculum are designed to help students excel at the collegiate level. Moreover, these classes increase your potential in related subject areas, for instance, science.

Although the general requirement is three years of math coursework, you may have to take four for specific colleges. If you are intending to major in a field that does not need advanced math, you may opt-out of it. In such cases, students should take classes related to their field of study, meanwhile fulfilling the least math requirements. However, if you are someone

intending to major in the STEM field, there is no time better than high school to learn advanced concepts.

If you are wondering what high school math classes should make it to your list, read on.
